PN532/C1
Near Field Communication (NFC) controller
7.1.5 Card operating modes
The PN532 can be addressed like a FeliCa or ISO/IEC 14443A/MIFARE card. This means
that the PN532 can generate an answer in a load modulation scheme according to the
ISO/IEC 14443A/MIFARE or FeliCa interface description.
Remark: The PN532 does not support a secure storage of data. This has to be handled
by a dedicated secure IC or a host. The secure IC is optional.
Remark: The PN532 can not be powered by the field in this mode and needs a power
supply.
7.1.5.1 ISO/IEC 14443A/MIFARE card operating mode
With appropriate firmware, the PN532 can handle the ISO/IEC 14443A including the level
4, and the MIFARE protocols.
The following diagram describes the communication at the physical level. Table 10
describes the physical parameters.
